Abstract

PURPOSE:To provide a granular deodorant having superior deodorizing action made of a powdery carrier contg. an extract or a fraction from a plant of a camellia family and at least as a partial component a polymer high in water absorptivity. CONSTITUTION:An extract or a fraction is drawn out principally from the leaves of a plant of the camellia family, such as tea, sadzanqua, camellia, sakaki, or laurel. A granular deodorant is prepared by using said extract or fraction weighing 0.01-30% and 99.99-70wt% granular carrier contg. at least as a partial component a polymer high in water absorptivity. This polymer is added to said carrier by its 1-30wt%. As said carrier, diatomaceous earth, kaolin, zeolite, bentonite, etc. are used, and as said polymer, crosslinked polyethylene oxide, cross-linked polyvinylpyrrolidone, cross-linked sulfonated polyethylene, etc. are used.

Description

[Detailed description of the invention] This relates to a granular deodorant.

Garbage generated from the kitchen must be stored in a garbage container until the garbage collection day, but the fl+J emits a foul odor such as rotten or rancid odor, causing an unpleasant feeling to the surrounding area. However, no significant countermeasures have been taken in the past.

Also, when applying fertilizers such as oil cake to gardens and indoor plants, 1 to 2
There is a distinctive odor that wafts up during the day, but few measures have been taken to eliminate this odor.

The object of the present invention is to effectively eliminate this type of bad odor.

The present invention resides in a powdery deodorant comprising a powdery or granular carrier (B) containing at least a portion of an extract or fraction (5) of a camelliaceae and a superabsorbent polymer, such as those listed below. It has excellent effects.

(1) Placing a book over food scraps or fertilizer after fertilization will immediately and effectively eliminate bad odors.

(2) Since the deodorizing component is attached to the powder carrier, it has a sustained release property and the deodorizing effect lasts for a long time.

(3) It is easy to handle because it can be simply ratified, and it is easy to store because it is in powder form.

(4) Not only does it adsorb and remove newly generated odors, but it also absorbs moisture in the odor source and significantly slows down the progress of rot.

The camellia plant extract or fraction (5) in the present invention refers to an extract or distillate mainly from the leaves of tea, sasanqua, camellia, sakaki, hirakaki, laurel, etc., and includes flavanols, flavonols, and 714. i! It has the following characteristic values.

) Value measured in a glopylene glycol solution) As a super absorbent polymer contained in a granular carrier (B) containing at least a portion of a super absorbent polymer, the amount of the super absorbent polymer is several tens to hundreds of times its own weight, or A polymer that absorbs and retains more than 1,000 times more water (100% water)
For example, polyethylene oxide crosslinked product, polyvinylpyrrolidone crosslinked product, sulfonated polyethylene crosslinked product, saponified dengue-(meth)acrylonitrile graft copolymer, hydrolyzed crosslinked polyacrylamide, self-crosslinked polyacrylic mti, starch-(meth)acrylic acid Crosslinked salt copolymer, polyvinyl alcohol crosslinked product, vinylnisder-unsaturated carboxylic acid (ester) copolymer resin, edylene-vinyl ester-unsaturated carboxylic acid (ester) copolymer saponified product, Saponified products of hydroxyargyl acrylate acrylamide copolymer are available.

The granular carrier (B) may be only a superabsorbent polymer, but it is usually used in combination with other decayed granules. Other suitable powders include clay minerals such as silica gravel, kaolin, zeolite, and bentonite, which have excellent adsorption ability for the component (A), as well as calcium carbonate,
Talc, silicon dioxide, mica, calcium silicate, aluminum silicate, magnesium oxide, titanium oxide, zinc white, magnesium carbonate, barium sulfate, calcium sulfate, sodium sulfate, wood flour, cork powder, bulb, dextrin, grain flour , grains, and weft powder are used.

The blending ratio of the plant extract or fraction (A) and the particulate carrier (B) containing at least a portion of highly water-absorbing i\ molecules can vary widely as long as the mixture is in the form of powder, but preferred options may vary. Shikke (A) O, O]~30wt-M%, (B) 9999~7
0% by weight, particularly preferably (A) 0.1-10%, and (A) 99.9-90%. If the proportion of (A) is too low, the deodorizing effect will be lacking, and if the proportion of (A) is too high, it will be difficult to form a powder or granule that is easy to spread, and this will be economically disadvantageous.

In addition, it is sufficient that the superabsorbent polymer accounts for at least a part of the powder/grain carrier (B), but it is better to use the super absorbent polymer in combination with other powder/grain carriers than to use the super absorbent polymer alone, since the deodorizing component The holes have a deodorizing effect of 11. In addition, it is preferable because it is not sticky and is advantageous in terms of cost. Therefore, when the entire particulate carrier (B) is 100 parts by weight, it is highly practical to select the amount of super absorbent molecules from the range of 0.1 to 30 parts by weight.

Upper %: (A) and (I3) are mixed by spraying or dropping the diluted solution of (G)) into (G)).
Done in any way.

The powdery deodorizer of the present invention (: ↓, sprayed on odor sources in garbage containers, urine tanks, portable toilets, etc., or sprinkled on top of fertilizer in storage or fertilizer after fertilization, It can be widely applied as a deodorizing agent to various odor sources, such as residues from pulp factories, food factories, and leather factories, the remains of laboratory animals, the shells of live oysters after processing, and surplus activated sludge.

Next, the powdery deodorant of the present invention will be further explained with reference to Examples. The numbers 1 prisoner and 1-%j below are based on the Chōshun standard.

18 parts The above mixed powder of B1, B2 and B8 was sprayed with an aqueous solution and then dried with hot air at about 70°C. The obtained powdered deodorant was subjected to the following deodorization test (r).

Deodorization test Food waste generated from the kitchen was poured into a plastic container with a capacity of 40fi for 7 minutes, and the above powdered deodorizer about IOG was sprinkled on top of the container and the container was covered with a lid. The lid was then opened over time and the odor was detected by six trained panelists. Note that the odor intensity was judged on the following six levels.

Odor intensity 0... No odor 1... Smell you can barely detect 2... Weak odor that you can tell what it is 3...
Easily perceivable odor 4...Strong odor 5...Intense odor The results are shown in Table 1.

Control Examples 1 to 2 When no deodorant was sprayed (visceral example 1), when a mixed powder consisting of BB and B8 without A was sprayed (control example 2), even with K, Example 1 A deodorization test was conducted in the same manner as above.
